1 Claim.

'I'his invention relates to toy or model airplanes and my improvements are directed to means for the simple and economical construction and assembly of the parts thereof.

Essentially my invention consists in forming the fuselage of such toy airplane from a single sheet of buckram or other suitable stiif, mouldable material, whose opposite edges are cemented together to constitute a closed hollow body, of light weight and having suflicient strength to the usage to which the toy airplane is put.

Also the fuselage, as formed, includes a'vertical stabilizer by suitably shaping opposite rear portions of the sheet, bringing said portions into ply relation and cementing them together, the doubled thickness giving increased rigidity to this vertical stabilizer. y

Also the moulded fuselage is provided with respective means for carrying the supporting airfoil and the horizontal stabilizer.

Further the moulded fuselage is equipped at its nose with a removable bearing cap for the propeller shaft, and said fuselage, at its rear under surface has localizing means for engaging the terminal hoek of the power band.

Still lfurther the moulded fuselage at its forward under surface, is provided with a fitting for the releasable engagement of a bent wire which carries the landing wheels.

Other features of my invention will hereinafter appear. I

In the drawings.:

Figure 1 is a plan view, partly broken away, of my improved toy airplane.

Fig. 2 is a side sectional view thereof.

Fig. 3 is a partial detail perspective view,

. showing the means for removably connecting the landing gear.

Fig. 4 is a section on the line 4-4 of Fig. 2.

Fig. 5 is a section on the line 5-5 of Fig. 2.

Fig. 6 is a perspective elevation of the toy alrplane having modified means for detachably connecting thereto the wing and horizontal stabilizer, and

Fig. 7 is a side view, partly in section, of Fig. 6.

In Figs. 1 to 5, illustrating my invention in one form thereof, let I indicate the fuselage, 2 the supporting airfoil, 3 the horizontal stabilizer, 4

the vertical stabilizer, 5 the propeller, having.

shaft 6 and power/band 1, 8 the shaft bearing member, and 9 the landing gear.

One feature of my invention consists in the I formation of the fuselage from a single sheet of stiff, mouldable material, such for example as buckram, which material is" cut to the desired configuration and then moulded into the hollow, fuselage contour indicated in the drawings, with its opposed edges I0 cemented together to complete the formation. 5 At the rear of the hollow fuselage structure the opposite end portions f the sheet material which are preformed as indicated, are brought together, in ply form, and united by cement to thus constitute the vertical stabilizer 4.

In the moulding of the fuselage reinforce ribs II, I2, are formed, extending respectively longitudinally and transversely, these ribs stiffening the hollow structure and aiding to maintain its contour against deformation. 15

The nose of the fuselage is provided with a metallic annulus I3 which is adapted for the reception of a removable plug or button constituting the bearing member 8 that has an axial orifice to receive the propeller shaft 6. Said 20 shaft 6,-which carries propeller 5, has a terminal hook I4 that engages the power band 1.

The other end of the power band is engaged by a` hook I5 which itself is engaged in an eyelet I6 that is secured in the under surface of the 25 fuselage, at the rear thereof. y

The landing gear 9 consists of a bent wire whose respective ends carry the wheels and whose doubled centre is angled and adapted to fit slidably in a socket Il formed on a plate I8 which 30 has lugs`|9 that are clamped to the fuselage at its forward under surface.

The supporting airfoil, or wing 2 is removably connected to the fuselage in the example of Figs.

l to 5, by passing it through aligned slots 20 35 formed in the opposite sides of the fuselage and centering it therein, the depth of said slots being such that the wing will be frictionally held therein.

Also, toward the rear of the fuselage other slots 40 2I are provided for the like reception of the horizontal stabilizer 3.

In the modied form of my invention illustrated in Figs. 6 and 7, all the structural parts of the toy airplane -are identical with those of 45 Figs. 1 to 5, 'excepting only that the modes of connecting the wing and horizontal stabilizer differ. Thus, in Figs. 6 and 7 the under surface of the fuselage is provided with jogs or steps 22, o 23. The wing 2 is fitted against the fuselage bottom behind step 22, and the stabilizer 3 is fitted against the fuselage bottom behind step 23. In order to localize the wing and stabilizer respective rubber bands 24, 25 are placed about 55 the fuselage and said elements in the usual manner common in this art.

Also, in these views the vertical stabilizer l is shown as provided with moulded reinforce ribs Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.

I claim:-

10 In a toy airplane, a fuselage composed of relatively stiff sheet material shaped and moulded in hollow form and having its meeting edges presenting flanges and secured together, the flanges at the upper rear portion of said fuselage being extended and shaped to form a vertical stabilizer of double thickness with walls in immediate contact to aord increased rigidity, the anges and stabilizer being'in the same plane.
